True or False: Removing foliage below the water line in a vase discourages bacteria development.

Removing foliage below the water line in a vase is indeed a beneficial practice that discourages bacteria development. When leaves and stems are submerged in water, they can decay and produce organic matter, which serves as a food source for harmful bacteria. This bacterial growth can negatively affect the water quality and shorten the lifespan of the cut flowers.

By trimming away any leaves or foliage that would be in contact with the water, you not only prevent the decomposition of organic material but also keep the water cleaner for the flowers. Cleaner water enhances the ability of the stems to take up water and nutrients, promoting healthier, longer-lasting flowers.

Maintaining good water quality is essential in floral arrangements, and this simple step significantly contributes to the overall health and preservation of the arrangement. Other options suggest variability depending on flower types or imply that there may be exceptions, but the principle of preventing bacterial growth through the removal of submerged foliage is applicable across a wide range of floral species.
